The Who - Heaven and Hell (Tanglewood 1970)

At some point in the late 1970s, I believe, The Who began to open their shows with "I Can't Explain." But during the "Tommy Era," the band kicked off live performances with "Heaven and Hell" which was written by bass player John Entwistle. The above video is the song synced up with the footage of the concert at Tanglewood in 1970. For a while, the band opened with another Entwistle song, "My Wife."
